Cocos3 -- 4. js hot update, cocos34.js hot

1. launch. js code:

// Launch: update filesvar _ failCount = 0; var AssetsManager = cc. scene. extend ({_ am: null, _ progress: null, _ percent: 0, _ percentByFile: 0, run: function () {// windows may not need update var not_update; if (cc. sys. OS = sys. OS _WINDOWS) {not_update = 1;} if (not_update |! Cc. sys. isNative) {this. loadGame (); return;} var layer = new cc. layer (); this. addChild (layer); this. _ progress = new cc. labelTTF. create ("download progress: 0%", "Arial", 12); this. _ progress. x = cc. winSize. width/2; this. _ progress. y = cc. winSize. height/2 + 50; layer. addChild (this. _ progress); // android:/data/com. huanle. magic/files/var storagePath = (jsb. fileUtils? Jsb. fileUtils. getWritablePath ():". /"); // storagePath indicates the local storage directory. The updated files will be downloaded to this directory. When the program loads scripts and resources, this directory will be preferentially queried. _ am = new jsb. assetsManager ("res/project. manifest ", storagePath); this. _ am. retain (); if (! This. _ am. getLocalManifest (). isLoaded () {cc. log ("Fail to update assets, step skipped. "); this. loadGame ();} else {var that = this; var listener = new jsb. eventListenerAssetsManager (this. _ am, function (event) {switch (event. getEventCode () {case jsb. eventAssetsManager. ERROR_NO_LOCAL_MANIFEST: cc. log ("No local manifest file found, skip assets update. "); that. loadGame (); break; case jsb. eventAssetsManager. UPDATE_PROGRESSION: that. _ percent = event. getPercent (); that. _ percentByFile = event. getPercentByFile (); cc. log (that. _ percent + "%"); var msg = event. getMessage (); if (msg) {cc. log (msg);} break; case jsb. eventAssetsManager. ERROR_DOWNLOAD_MANIFEST: case jsb. eventAssetsManager. ERROR_PARSE_MANIFEST: cc. log ("Fail to download manifest file, update skipped. "); that. loadGame (); break; case jsb. eventAssetsManager. ALREADY_UP_TO_DATE: case jsb. eventAssetsManager. UPDATE_FINISHED: cc. log ("Update finished. "); that. loadGame (); break; case jsb. eventAssetsManager. UPDATE_FAILED: cc. log ("Update failed. "+ event. getMessage (); _ failCount ++; if (_ failCount <5) {that. _ am. downloadFailedAssets ();} else {cc. log ("Reach maximum fail count, exit update process"); _ failCount = 0; that. loadGame ();} break; case jsb. eventAssetsManager. ERROR_UPDATING: cc. log ("Asset update error:" + event. getAssetId () + "," + event. getMessage (); that. loadGame (); break; case jsb. eventAssetsManager. ERROR_DECOMPRESS: cc. log (event. getMessage (); that. loadGame (); break; default: break;}); cc. eventManager. addListener (listener, 1); this. _ am. update (); cc. director. runScene (this);} this. schedule (this. updateProgress, 0.5) ;}, loadGame: function () {cc. loader. loadJs (["src/game. js "], function (err) {if (err) {cc. log ("error:" + err);} else {// run game logic game. run () ;}}) ;}, updateProgress: function (dt) {this. _ progress. string = "download progress:" + this. _ percent + "%" ;}, onExit: function () {this. _ am. release (); this. _ super ();}});

After the update, src/game. js is loaded, and game. run runs the main logic of the game. All the logic starts from there.

2. Configuration File

Add project. manifest in the res directory of the client:

{      "packageUrl" : "http://192.168.1.103/bw",    "remoteManifestUrl" : "http://192.168.1.103/bw/project.manifest",    "remoteVersionUrl" : "http://192.168.1.103/bw/version.manifest",    "version" : "1.0.0",    "groupVersions" : {        "1" : "1.0.0"      }  } 

The server can use everything to build http for testing:

Project. manifest:

{      "packageUrl" : "http://192.168.1.103/bw",      "remoteManifestUrl" : "http://192.168.1.103/bw/project.manifest",      "remoteVersionUrl" : "http://192.168.1.103/bw/version.manifest",     "version" : "1.0.5",      "groupVersions" : {          "1" : "1.0.5"      },    "engineVersion" : "3.0 rc0",      "assets" : {          "src/app.zip" : {"md5" : "6809C100A369FD8A79A97208B0278A2B",            "compressed" : true,            "group" : "1"          }      },      "searchPaths" : [          "src/"]  } 

Version. manifest:

{"packageUrl" : "http://192.168.1.103/bw","remoteManifestUrl" : "http://192.168.1.103/bw/project.manifest","remoteVersionUrl" : "http://192.168.1.103/bw/version.manifest","version" : "1.0.5","groupVersions": {"1" : "1.0.5"},"engineVersion" : "3.0 rc0"}
